Mechanism of hydraulic fracture propagation and fracturing process optimization in thin-interbedded sandstone-shale reservoirs based on 3D discrete lattice method
Published 2025-05-01“…When the ratio is <0.5, the fracture propagation is suppressed, while when the ratio is >1, the fracture propagation is promoted; 2) The minimum horizontal ground stress difference between layers is more than 7 MPa, which can effectively inhibit the propagation of cracks through layers; 3) The combination of a high-viscosity fracturing fluid (≥40 mPa·s) and a high injection rate (≥8 m3/min) enhances fracture penetration, while the “high-low viscosity” combined injection strategy collaboratively optimizes primary fracture expansion and weak interzonal surface opening. …”
